MEMORANDUM-CLIP FOR TELEPHONES.

Specification of Letters Patent.

Patented Got. 1, 1918.

Application filed April 13, 1917. Serial No. 161,896.

To all whom it may concern:

Be it known that I, Jnssn D. LANGDON, a citizen of the. United States, residing at Waterville, in the county of Douglas and State of Washington, have invented certain new and useful Improvements in Memorandum- Clips for Telephones, of which the following is a specification. I

My invention relates to an improved attachment for telephones for the purpose of furnishing new and novel means of holding, in a convenient and desirable position, memorandum or other data in proximity to the telephone and the telephone transmitter.

My further aim is to provide a convenient means of attaching a spring clip to accomplish the purpose hereinafter described.

These and other aims and advantages of my invention will more fully appear as the nature of the invention is more clearly understood from the following specifications, the subject matter of the claim and the adopted views illustrated in the accompanying drawings.

Figure 1 is a side view of the telephone transmitter showing one method of applying my invention thereto.

Fig. 2 is a front View showing mouthpiece of transmitter cut away, showing one way of holding the clip in operative position by spring contraction against mouth piece.

Fig. 3 represents front view of clip dismounted, for the purpose of showing retaining arms.

I desire to state that, for the sake of clearness and convenience in illustrating the application of my invention, I have adopted only one of the various methods of application to accomplish my purpose.

I'do not therefore restrict my invention to the exact details as herein shown and described, as my invention is capable of several methods of application, and I may resort to alterations and variations therein as I may deem expedient to the best application and construction of my invention to meet with the exigencies ofthe case,,without departing from the spirit of the invention, or the scope of the claim.

One method by which I attain the desired Copies of this patent may be obtained for result of my invention is illustrated in Fig. 1 of the drawings and wherein is that part of an ordinary telephone suflicient to show application of my invention and comprises the transmitter diaphragm container 1, transmitter front cover or face plate 2, having mounted thereon transmitter mouth piece 3.

The foregoing described parts are well known features of the conventional type of the telephone transmitters of an ordinary telephone and I employ in combination therewith a spring clip, having a tension clip at elastically tensioned against face plate 2 in the manner shown.

Fig. 3 represents front view of clip dismounted, retaining arms 55 the spring tension of which holds the same into operative position by spring tension exerted around mouth piece 3, on account of its bell shape and pressure exerted by retaining arms; when clip is placed in the manner shown the convex face of tension clip is held in contact with face plate 2.

I preferably place the retaining arms 5-5 around the mouth piece 3 at a point where it begins to widen toward the bell end, thereby causing a greater tension to be exerted toward surface or face plate 2 making a convenient holder for memorandum and other data when placed between clip 4 and face plate 2, thus accomplishing the purpose for which this invention was designed.

Having described my invention, what I claim is new and desire to secure by Letters-Patent, is

A memorandum clip for telephones consisting of a unitary, resilient sheet metal structure embodying spring arms for engaging the mouth piece of a transmitter, and a curved resilient clamping arm extending op.- positely to said first named arms and in a plane at right angles to the plane of said first named arms. and adapted to yieldingly bear against the face plate of the transmitter. Signed at San Francisco, California, this 24th day of March 1917.
